Apoplexy

Apoplexy is bleeding into an organ or loss of blood flow to an organ. For example,

  • Adrenal apoplexy: Bleeding into the adrenal glands
  • Pituitary apoplexy: Bleeding into the pituitary gland

Apoplexy refers to stroke symptoms that occur suddenly. Such symptoms occur due to bleeding into the brain. It can also occur by a blood clot in a brain blood vessel. Conditions such as subarachnoid hemorrhage or stroke are sometimes called apoplexy.

Functional apoplexy is when a person appears to be having stroke-like symptoms. However, there is no brain defect.

    • Endocrine glands

      Endocrine glands - illustration

      Endocrine glands release hormones (chemical messengers) into the bloodstream to be transported to various organs and tissues throughout the body. For instance, the pancreas secretes insulin, which allows the body to regulate levels of sugar in the blood. The thyroid gets instructions from the pituitary to secrete hormones which determine the pace of chemical activity in the body (the more hormone in the bloodstream, the faster the chemical activity; the less hormone, the slower the activity).
